Windows 7: Cannot get on the internet - wired or wirelessly

I have a Sony Vaio with windows 7 OS (64bit), I have installed and ran several differnet antivirus and malware programs and found nothing. I ran a full virus Scan (Kasperksy anti-virus 2012) and no issues found, I tried to do a System Restore to earlier date (it failed), I can see that i have an issue with the WAN Miniport IKEv2 (It will not deinstall...to try and reinstall...it just errors), I get "Diagnostic Policy Service not running" every time i try to trouble shoot. I have even performed a system scan (cmd.exe....cfs/scannow) and it found nothing. I even bought a new USB wirelss adapter to try and get online and it doesnt work. I have tried to log on to the internet at work through our network as well as at home through my home netowork (two different providers) and nothing works. Any suggestions?
